Fort Lee Health Officer Steven Wielkotz told the newspaper that more than 100 pigeons had descended on the borough two months ago, and he wanted to implement a more humane option than trapping and killing pigeons. Wielkotz invested in Avitrol seeds that poison birds, told by an exterminator that the seeds were too big for any other bird to eat, according to the report. But while he was intended to just kill one or two pigeons and scare the rest away, several blackbirds ate the seed, and some were spotted suffering, the report said.
